Description

Technical Field

[0002] In the machining industry, the condition of the tool directly affects the machining quality and production efficiency. Traditional tool inspection methods often rely on manual inspection, which is not only time-consuming and labor-intensive, but may also lead to inaccurate inspections due to human factors, making it difficult to detect tool wear or breakage in a timely manner. In addition, traditional inspection methods usually need to be performed outside the machining process, which not only increases the production cycle, but may also cause quality problems during the machining process due to poor tool condition, and even cause safety accidents.

[0003] With the continuous advancement of science and technology, competition in various industries is becoming increasingly fierce. In order to improve processing efficiency, save time and save costs, this broken tool detection device was invented and designed. This broken tool detection is installed on the tool magazine. During the processing, the tool is detected to see if it is broken before changing the tool. At present, most broken tool detection devices are installed on the workbench or protective cover. When detecting whether the tool is broken, it takes processing time. If there are many tools and the tool changes are frequent, the tool detection will take up a lot of processing time, which is inefficient and wastes a lot of resources.

DETAILED DESCRIPTION

[0038] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments of the present application, all other embodiments obtained by ordinary technicians in this field without making creative work belong to the protection scope of the present application. It is understandable that the drawings are only provided for reference and illustration, and are not used to limit the present application. The connection relationship shown in the drawings is only for the convenience of clear description and does not limit the connection method.

[0039] Specifically, Figure 1-3As shown, in an embodiment of the present application, there is provided a broken tool detection device which does not occupy the processing cycle. The device is mainly composed of a tool magazine device 100 and a detection device 400. A tool 120 is installed in the tool magazine device 100. The tool 120 in the embodiment of the present application is a milling cutter, reamer or other type of tool 120. The tool 120 is installed on a conveyor belt through a mounting part 110 arranged on the tool magazine device 100, so that the tool 120 can be moved by the conveyor belt.

[0040] A support member 200 is provided on one side of the tool magazine device 100, and the support member 200 is fixedly connected to the tool magazine device 100. A linear drive device 300 is provided on the support member 200 at one end away from the tool magazine device 100, and a detection device 400 is provided on the linear drive device 300. The detection device 400 detects the length of the tool 120 on the tool magazine device 100.

[0041] Specifically:

[0042] In the present application, a linear module 310 is installed on the linear drive device 300, a linear slot is opened on the linear module 310, a driving rod 312 is installed in the linear slot, and the driving rod 312 is connected through a driver 320 on one side of the linear slot, so that the driving rod 312 is driven on the linear module 310 by the driver 320.

[0043] A driving member 311 is provided on the linear module 310, and the driving member 311 is connected to the driving rod 312, so that when the driver 320 is driven, the driving rod 312 can drive the driving member 311 to move on the linear module 310. In order to ensure that the driving member 311 moves linearly, the driving member 311 is limited by the linear groove, so that the driving member 311 can only move along the direction of the linear groove, and the moving direction is the direction of the driving member 311 on the linear module 310 toward or away from the tool magazine equipment 100.

[0044] In the embodiment of the present application, preferably, the driver 320 is configured as a driving motor, which drives the driving rod 312 to rotate in the linear groove. At the same time, the driving rod 312 is sleeved and threadedly connected to the driving member 311. Through the limiting relationship between the driving member 311 and the linear groove, when the driving rod 312 rotates, the driving member 311 is driven to move along the direction of the linear groove.

[0045] In the embodiment of the present application, preferably, the driver 320 can be configured as a linear driver 311, which drives the driving rod 312 to move linearly along the direction of the linear groove. The driving member 311 is fixedly connected to the driving rod 312 to drive the movement of the driving member 311.

[0046] A detection device 400 is arranged on the driving member 311, and the detection device 400 moves along the direction of the linear groove through the connection of the driving member 311. Figure 2-3 shown.

[0047] The detection device 400 in the present application is provided with a mounting base 420 and a proximity switch 430. The mounting base 420 is directly arranged on the driving member 311. The mounting base 420 can be moved by the movement of the driving member 311. The above-mentioned detection tool rod 410 is arranged on the mounting base 420. The detection tool rod 410 can be moved in a direction toward or away from the tool magazine device 100 through the mounting base 420, and its movement is mainly achieved through the driver 320.

[0048] A proximity switch 430 is also provided on the driving member 311 . The proximity switch 430 is a part of the detection device 400 and is used to measure the moving distance of the detection tool rod 410 to determine the length of the tool 120 to be detected.

[0049] Specifically:

[0050] The proximity switch 430 is arranged at the side position of the detection knife rod 410, and a sensing member 411 is arranged on the detection knife rod 410. The sensing member 411 is arranged in a cylindrical structure in the present application, and is sleeved outside the detection knife rod 410, so that the sensing member 411 moves with the movement of the detection knife rod 410, and the radius of the sensing member 411 in the embodiment of the present application is large so as to ensure that when the detection knife rod 410 moves to a certain position, the sensing member 411 can be sensed by the proximity switch 430, and when the proximity switch 430 senses the sensing member 411, the detection device 400 generates a contact signal.

[0051] Specifically:

[0052] An abutment member 412 is provided on the end of the detection tool rod 410 facing the tool magazine device 100, and the abutment member 412 can contact and abut the tool to be tested 120 on the tool magazine device 100. The driver 320 is started, and the driver 320 drives the driving member 311, the detection tool rod 410 and the proximity switch 430 to move in the direction toward the tool magazine device 100. When the abutment member 412 on the detection tool rod 410 contacts the tool to be tested 120, the detection tool rod 410 is abutted by the tool to be tested 120. At this time, the driver 320 also drives the driving member 311 to move. The sensing member 411 provided on the driving member 311 is abutted by the tool to be tested 120, so that the position of the sensing member 411 remains relatively unchanged, so that the driving member 311 drives the mounting base 420 and the proximity switch 430 to move. Movement, in the embodiment of the present application, the total distance moved by the driving member 311 is set to x1. Since the tool 120 is fixed in the tool magazine device 100, the position of the tool 120 at one end of the tool 120 device is at the same distance from the driver 320, that is, the x1 value is a fixed value during the detection process. On the driving member 311, due to the relative limit position between the proximity switch 430 and the sensing member 411, the proximity switch 430 and the sensing member 411 maintain the closest distance without being sensed. When the sensing member 411 starts to move relative to the proximity switch 430, the proximity switch 430 immediately generates a contact signal, and the distance moved by the driving member 311 when the contact signal is just generated is set to x2. At this time, the length value X=x1-x2 of the tool 120 to be measured can be calculated based on the two values.

[0053] Among them, in the embodiment of the present application, before detecting the tool 120, a standard tool 120 length is preset in the controller in the detection device 400. During the detection, the tool 120 length X is compared with the standard length to determine whether the tool 120 to be tested meets the standard error. In the embodiment of the present application, according to different detection standards, the tool 120 length error is controlled within 5% and is a qualified tool 120.

[0054] In the above, an elastic member 413 is sleeved on the detection blade rod 410 , one end of the elastic member 413 abuts against the abutting member 412 on the detection blade rod 410 , and the other end of the elastic member 413 abuts against the mounting base 420 .

[0055] The elastic member 413 can be provided to quickly reset the detection knife rod 410 after the measurement is completed, so as to facilitate the next measurement.

[0056] At the same time, in the embodiment of the present application, a limiting device 500 is provided on the linear drive 320 at one end thereof facing the tool magazine device 100. Figure 3As shown, the limiting device 500 specifically includes a limiting buffer 510, and a limiting plate 520 is set at one end of the limiting buffer 510 away from the linear module 310. When the driving member 311 abuts against the limiting plate 520, the sensing member 411 and the proximity switch 430 are disconnected from the sensing.

[0057] Among them, under the above structure, if Figure 4 As shown, the following detection steps are included in this application:

[0058] Step 1: Install the tool 120 to be tested into the tool magazine device 100, and move the tool 120 in the tool magazine device 100;

[0059] Step 2: Start the driver 320, which drives the driving rod 312 to rotate, so that the driving member 311 moves linearly on the linear module 310, and the moving driving member 311 drives the detection tool rod 410 to move toward the position of the tool to be tested 120 until the detection tool rod 410 abuts against the tool to be tested 120;

[0060] Step 3: The driver 320 drives the detection blade rod 410 to continue to move linearly, and when the proximity switch 430 and the sensing element 411 begin to sense each other, the detection device 400 outputs a contact signal;

[0061] Step 4: When the controller receives the contact signal, the controller records the moving distance of the driving member 311 , and calculates the length value of the tool 120 to be measured according to the moving distance of the driving member 311 .

[0062] The above embodiments are only used to illustrate the technical method of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical method of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical method of the present invention.
